The AD7542 is a precision 12-bit CMOS multiplying DAC designed for direct interface to 4- or 8-bit microprocessors. The functional diagram shows the AD7542 to consist of three 4-bit data registers, a 12-bit DAC register, address decoding logic and a 12-bit CMOS multiplying DAC. Data is loaded into the data registers in three 4-bit bytes, and subsequently transferred to the 12-bit DAC register. All data loading or data transfer operations are identical to the WRITE cycle of a static RAM. A clear input allows the DAC register to be easily reset to all zeros when powering up the device. * Resolution: 12 Bits * Nonlinearity: ±1/2 LSB Tmin to Tmax * Low Gain Drift: 2ppm/°C typ, 5ppm/°C max * Microprocessor Compatible * Full 4-Quadrant Multiplication * Fast Interface Timing https://elecena.pl/product/5067622/precision-12-bit-cmos-multiplying-i-dac-4-bit-bus 2015-03-29 https://elecena.pl/product/5067622/precision-12-bit-cmos-multiplying-i-dac-4-bit-bus 2018-03-29 https://elecena.pl/product/5067622/precision-12-bit-cmos-multiplying-i-dac-4-bit-bus 2025-01-18
